(2) After making certain the old bulb is cool to thetouch, remove it by pulling straight out of its socket.Do not twist as the lamp pins may break off and staylodged in the socket.

(3) Handle the new bulb only with tissue paper or theplastic in which it is wrapped and insert the two pinsinto the two holes in the socket.

DO NOT HANDLE WITH BARE FINGERS BULB MAY EXPLODE WHEN HEATED IF NOT TREATED CORRECTLY.

CARE

Always cover the instrument with plastic dust cover provided when the microscope is not in use.

Keep eyepieces in the microscope body at all times in order to prevent dust from falling on the internaloptics.

Store the microscope in a safe, clean place when not in use for an extended period of time.

CLEANING

Clean exposed lens surfaces carefully with a pressurized air source, soft brush or clean soft cloth. Toomuch finger pressure may damage lens coatings.

To remove oil, fingerprints and grease smudges, moisten the cleaning cloth with a very small amount ofalcohol or xylene.

Immersion oil should always be promptly cleaned from high power oil immersion objectives after everyuse.

Painted or plastic surfaces should be cleaned only with a cloth moistened with water and a smallamount of detergent.

DO NOT ATTEMPT TO MAKE ADJUSTMENTS TO THE INTERNAL OPTICS OR MECHANICS !!

CAMERA OPERATION

(1)Fix your 35mm SLR camera, T2 Adapter and a photo (camera) eyepiece on the MA150/50 orMA150/60 Camera Attachment, then mounting this assembly on the straight tube of the trinocular body.

(2)Pull out the lever on your trinocular body so as to send the image both to the camera and the visualeyepieces.

(3)Rotate the adjustment ring on the straight tube so as to set correctly for optimum conditions ofsimultaneous visual observation and photography.

TELEVISION

For television the MA151/10 C Mount should be used, threaded into your TV camera, then placedand adjusted on straight tube of your trinocular body.

Adjustment can then proceed as per paragraph(3) above. You should understand that the comparativelylarge magnification factors inherent in most TV camera/monitor systems will restrict your field of view(while blowing up total magnification).

A correct optical set-up and adjustment is, of course, crucial to obtaining a good TV monitor image, butkeep in mind that the monitor controls for brightness and contrast adjustment are also important andshould also be experimented with in order to obtain the best monitor image.

MAINTENANCE AND CARE

BULB REPLACEMENT

When changing light bulbs in the illuminators, always disconnect the plug from the electrical source, andmake it sure that the green monitor light is off. Never work on the electrical system without firstdisconnecting. The bulb is held in a socket block inserted in the light source housing at the back of theReflected Light Illuminator.

TRANSMITTED LIGHT ILLUMINATOR

(1)Remove the socket block from the microscope base by unscrewing the Screws @2 and pulling the Backing plate @3 clear of the instrument.

(2)After making certain the old bulb is cool to the touch,remove it by pulling straight out of its socket. Do not twist asthe lamp pins may break off and stay lodged in the socket.

UNPACKING, ASSEMBLY, PREPARATION FOR USE

UNPACKING

All MEIJI TECHNO microscopes are usually supplied in an expanded polystyrene, 2-part case and thisshould be used for storage, possible transport in the future, etc. If your order includes a woodenstorage cabinet, release the fixing screws holding the limb and base from the cabinet and withdraw.

Unpack the microscope and its parts carefully. Do not throw away any boxes or packing materials untilthe contents of the shipping container have been checked against your order and the packing list sent.

ASSEMBLY

REFLECTED LIGHT ILLUMINATOR, unpacked from the separate case, goes onto the microscope limbin the following way:

(1)Loosen the Clamp Screw of the femal cone-fitting at the Limb top.

(2)The male cone-fitting of Vertical Illuminator is mounted into the femal cone-fitting at the limb top so the Clamp Screw gears into the slot of the male cone-fitting. Now, screw it up by the sameClamp Screw . The above gearing secures the right position of REFLECTED LIGHT ILLUMINATOR.

(3)Likewise, mount the Viewing Head into the female cone-fitting of Vertical Illuminator, gearing the slot and the Clamp Screw .

Place the microscope and parts on a sturdy table or desk which gives firm and stable support. Thisshould be located in the atmosphere as clean as possible, avoiding the places where there is excessivedust, moisture, heat or fumes.

Note: It is important that you change magnifications by rotating the milled nosepiece ring, not bygrasping and pulling the objective barrels. Doing this puts strain on the objective housings which cancause some decentering.

BERTRAND LENS

The ML9400 series polarizing microscope features an in-tube, slide-in Bertrand Lens. Fitted with it is afield-limiting aperture which allows isolation of small features in the center of the field. Thus thecharacteristic interference figures for small crystalline elements can be observed and studies. Theseeffects only occur when both analyzer and polarizer are in the optical path, the polarizer being set at 0degrees. The in-tube design of the Bertrand Lens makes it possible to use it equally well with binocular,trinocular and monocular bodies.

COMPENSATORS

A sensitive tint plate (first order red) and mica 1/4 wave plate are supplied with the ML9400 seriespolarizing microscope as standard. These are fitted in plates with standard DIN dimensions, sliding in aslot cut in the tube just above the objective nosepiece.

PHOTOGRAPHY AND TELEVISION

PHOTOGRAPHY

Photographic documentation of microscope visual images is most conveniently achieved by using thetrinocular (photo-binocular) bodies for use with 35mm SLR Camera or PMX100 Large Format Camera.

In the case of the ML series of biological, metallurgical and polarizing microscopes a trinocular body isequipped with a sliding switch-over beam-splitter component which either (1) allows all of the light to goto the visual eyepieces or (2) directs 80% of the image-forming light upwards to the film plane of a35mm SLR camera, while still sending 20% of the light to the binocular eyepieces.

In the system the MA150/50 or MA150/60 Camera Attachment should be used with the SLR camera ofyour choice. Please note that one of the large range of T2 Adaptor Rings suiting to your camera shouldbe ordered separately.

These adaptor rings are intended to compensate for the small differences in effective distance of thefilm plane in your camera - so as to ensure that photographs are optimally sharp, and achieved withoutwastage of film in trial shots and experimentation.

In addition special low-power camera eyepieces (2.5X, 3.3X and 5X) are available and recommended -these will give you maximum field coverage on your specimen while using the convenient andeconomical 35mm film format.

When in place insert eyepieces in the eyetubes of the binocular body and mount the objectives on thecentering objective nosepiece, starting with the lowest magnification, but positioning the 10X in the fixed(not centerable) opening. Then position the others to the right in order of increasing magnification.

A focusable cross-line eyepiece should be used in the slotted eyetube. Make sure that it is Keyedinto the slot in the eyetube, as its orientation is important and should not change. The cross-line shouldbe sharply focused by turning the focusing ring.

IMPORTANT! Before plugging the illuminator into any electric outlet, make sure that transformers and illuminationbases supplied to you are suitable to the current available (See voltage indication at the bottom of limb).

OPERATING INSTRUCTIONS

OPTICAL SET-UP AND TRANSMITTED LIGHT ILLUMINATION

(1)Turn on the Transmitted Light Illuminator by turning the Switch . Place the specimen slide you wishto examine on the microscope stage and rotate the 10X objective into position for focus.

(2) Move the substage condenser up to its top position, using the rack and pinion focusing control .Check to make sure that both the field iris and the aperture iris are fully open.

(3) Focus down on your specimen slide until detail can be seen. Adjust the brightness of the in-baselight source, using the intensity control knob , left-hand back on the base.

BINOCULAR ADJUSTMENT

Comment: Using a binocular body is much more efficient and less tiring than a monocular body, but itmust be adjusted correctly. When it is perfectly adjusted the images coming from the two eyepieces arefused into one better image in eyes of the observer.

BOTH TRANSMITTED AND REFLECTED ILLUMINATORS CAN BE USED SIMULTANEOUSLY FORTHE OBSERVATION OF SEMI-TRANSPARENT MATERIALS.

ROTATING STAGE

A ball-bearing circular stage, precisely rotatable through a full 360 degrees, is supplied as standard.With rotation angular measurements can be made, reading by a vernier to 0.1 degrees.

CENTERING OF OBJECTIVES

When the microscope is shipped to you the objectives are factory par-centered. Therefore, check andmake sure that the objectives have been precisely seated on the optical axis. If it is even lightly off axisthe centering is required with the Hexagon keys supplied in the following way:

(1) Focus down on your specimen through the 10X objective mounted in the non-centerable locked-upopening, aside from the other floating centerable nosepiece holes, and memorize the point of thespecimen appearing just on the eyepiece cross-line center.

(2)Turn the nosepiece and bring the next higher power objective to the position, and focus on thespecimen if necessary, and see whether the pinpoint of the specimen you memorized before is locatedjust at the cross point of the mark.

(3)In case the memorized pinpoint isseen away from the cross point, itmust be brought to the cross point bythe use of the provided two CenteringScrews, which can be inserted intothe key holes on the nosepiece ringand turned to move the pinpoint tothe cross point.

After you have focused on the specimen proceed as follows:-

(1)Move the sliders on which the two binocular eyepiece tubes are mounted in and out until thedistance between them is exactly the same as the distance between the pupils of the observers eyes.(This is the interpupillary distance .)

(2)When this is done, note the dimension which isdisplayed in the window of the slider. Alwaysremember to set to this distance when using themicroscope. It will be different for differentobservers, so they will have to check the bestsetting for themselves.

(3)Now use the fine focus to get a sharp image in the right-side eyepiece using your right eye.

(4)Using the left eye, adjust the diopter adjustment collar on the eyepiece in the left-hand eyepiecetube to get the sharpest possible image. Do not use fine focus.

(5)Now turn the field iris adjustment ring until thefield iris is seen in the field of view.

(6)Raise or lower the substage condenser so as tofocus the field iris as sharply as possible in the planeof your specimen. When this is done open out thefield iris until it is just outside the field of view.

(7)Removing one of the eyepieces, observe the disc of light coming from the back of the objective inuse. Close down the aperture iris , using the lever on the substage condenser, until only about 70%-80% of the disc of light observed remains visible. (Note that the microscope is now set up for use withthe 10X objective. Similar adjustments to those mentioned above should be made when using any ofthe objectives required.)

(8)Regarding the note above, if you choose the 100X objective, immersion oil must be applied to thespecimen slide so that, when this objective is swung in and focused, both the specimen slide and the100X objective are in good, bubble-free contact.

(9)The tension control knob is provided toallow the individual user to adjust the focustension to his/her own preference. Tension maybe increased by turning the knob with acounterclockwise motion. A lighter tension maybe set by turning clockwise.

SAFETY AUTO-STOP FOR OBJECTIVES AND STAGE PLATE

In order to protect specimen slides and objective lenses from accidental damage, the 20X or biggerpower lenses are designed to retract at the tip by built-in spring. Besides, Auto-Stopper is equipped inthe microscope limb for further safety.

HOW TO AUTO-STOP

(1) Make sure that the Auto-Stop lever is loose. Ifnot, please turn the lever counterclockwise to unlock.

(2) Focus the highest power objective onto thespecimen, and at the focused position, fasten the leverby turning it clockwise. Then, the stage plate can notgo up over the level set by the lever.

SPECIAL POLARIZING FACILITIES

Please note that the applications and detailed techniques of polarizing microscopy are beyond thescope of this manual. What follows is a description of the special features of the ML9400 SeriesPolarizing Microscope which are often used in geological, mineralogical, chemical and other opticalstudies which have long been associated with the polarizing microscope.

POLARIZATION UNDERTRANSMITTED LIGHT

The Reflector of the Reflected Light Illuminatorshould be removed from the light path by pulling theKnob of the Reflected Light Illuminator to the fullto get a brighter image.

The substage polarizer is fully rotatable with aswing-out, click-in mount. When the polarizer isswung out, the light is not polarized.

(This picture shows that substage polarizer is swung out.)

When the Polarizer is swung into the path and clicked into its correct position, the polarizer may berotated, sending polarized light within angles from 0-360 degrees up to the specimens. Angularsettings for 0 degrees and 90 degrees are marked and clicked on the mounting so that these commonsettings can be located quickly and precisely.

Substage Polarizer

The Analyzer is mounted in an in-tube slider which moves the analyzer in and out of the optical path.When “in”, and with the substage polarizer also “in” and set at 0 degrees, these elements are said to be“crossed” and the field of view is said to be “extinguished”. In this condition the field of view is dark -except for optically active elements in the field, which rotate the angle of polarization and thus becomevisible against a dark background. This is the basic advantage of a polarizing microscope.

POLARIZATION UNDER REFLECTED LIGHT

The Reflector of the Refelected Light Illuminator should be placed in the light path by pushing the Knobuntil the Reflector occupies the light path completely.

Turn on the Reflected Light Illuminator by turning the Dimmer on the front panel of the separateTransformer Box as Dimmer functions as ON-OFF switch, too.

When uneven illumination occurs on the field of view, bulb in the lamp house requires centering in thefollowing way:

To move the bulb vertically, loosen the Clamp Screw and turn the Backing plate clockwise orcounterclockwise slightly.

To move the bulb horizontally, turn theLamp Centering Control .
